Yeah. Grados are great for rock and metal, but no subbass. Unfortunately, there's nothing with good subbass extension that sounds quite like the SR80i.

Actually, Shure SRH940s are Ok with metal, a bit harsh on some tracks (especially if not recorded/mastered well) but it does do sub-bass and mid-bass in a clean way. There's also the Beyer T5p's and a few others from $50 to $1000 (from AKG 240MKII to Hifiman HE500, to Ultrasone Signature Pro, etc.)

I don't doubt there are other headphones that people like for rock and metal. But I still bet they don’t sound like Grados.
